My 2003 Ford Escape with the Duratec V6 has a slight oil leak. The Max Life red bottle really has helped the leak become a small drip over the last year or so I have been using it. Maxlife is a great product. To further bring that drip to a stop I am thinking of adding some Liqui Moly motor oil saver to the mix and to see what happens. As I read more about the brand Liqui Moly, it seems to be a decent oil. Does anyone here have real world experience with their oils? I currently use Maxlife red bottle in the Ford and Amsoil SS 5-30 in the two Nissan vehicles. Is this brand worth buying / trying or should I stick with what I've got?
